here I posted you 2 links to the free codec (the first one is for Win2000/XP,
in the second one you can choose which OS you want it for). The problem with DivX free is that you'll encode your videos with the DivX logo in the bottom right corner of the movie.
I suggest you to use XviD instead, it's freeware and latest versions works really better than previous ones and in some cases better than DivX
